Strange 156 2.4 JTD non start
Just recently my 53 plate JTD has been reluctant to start from cold and a couple of times has refused completely meaning a call to Green Flag. Basically the engine turns over fine but seems very reluctant to fire up, after holding the key over for a while (15-20 secs) she eventually fires up complete with a cloud of whitish smoke from the exhaust. On the occasions when she refused to fire at all the Green flag mechanic basically connected another battery ( so that I didn't drain mine completely) and we simply held the key over until it fired, something in the region of 30-40 secs. Once the engine is warm she starts fine. Whilst probably not relevent the times she refused to start she was on a slight downhill incline, otherwise she has been parked level.
She has just had a new alternater, battery and glow plugs so I'm at a bit of a loss as to what it could be. Any thoughts would be most welcome.
